Water softening is the removal of calcium, magnesium, and certain other metal cations in hard water. The resulting soft water requires less soap for the same cleaning effort, as soap is not wasted bonding with calcium ions. Soft water also extends the lifetime of plumbing by reducing or eliminating scale build-up in pipes
Ice cream makers may prepare the mixture by employing the hand-cranking method or by employing an electric motor. The resulting preparation is often chilled through either pre-cooling the machine or by employing a machine that freezes the mixture. An ice cream maker has to simultaneously freeze the mixture while churning it so as to aerate the ...
Trolamine salicylate (Aspercreme, Aspergel) is an organic compound with the chemical formula [HN(CH 2 CH 2 OH) 3] + C 6 H 4 (OH)(COO −).It is a salt of triethanolamine and salicylic acid, i.e. the compound consists of protonated triethanolamine and the conjugate base of salicylic acid, salicate.
This is accomplished by exchanging divalent cations (such as calcium Ca 2+ and magnesium Mg 2+) with highly soluble monovalent cations (e.g., Na + or H +) (see water softening). Another application for ion exchange in domestic water treatment is the removal of nitrate and natural organic matter. In domestic filtration systems ion exchange is ...
The reduction of blowdown by dealkalization keeps the water treatment chemicals in the boiler longer, thus minimizing the amount of chemicals required for efficient, noncorrosive operation. [2] Carbonate and bicarbonate alkalinities are decomposed by heat in boiler water releasing carbon dioxide into the steam.
White Mountain Products is a brand of ice cream makers in the Sunbeam products division. It is a subsidiary of Newell Brands. Thomas Sands started White Mountain Freezer Company in Laconia, New Hampshire, in 1872. In 1881 their factory was destroyed by fire.
Salicylate poisoning, also known as aspirin poisoning, is the acute or chronic poisoning with a salicylate such as aspirin. [1] The classic symptoms are ringing in the ears , nausea , abdominal pain , and a fast breathing rate . [ 1 ]
This makes aspirin different from other NSAIDs (such as diclofenac and ibuprofen), which are reversible inhibitors; aspirin creates an allosteric change in the structure of the COX enzyme. [2] However, other effects of aspirin, such as uncoupling oxidative phosphorylation in mitochondria, [3] and the modulation of signaling through NF-κB, are ...
